Unified Threat Management for your business network.
(UTM) firewall which provides a powerful security solution to protect business networks from
a wide range of threats. The DFL-870 oﬀers a comprehensive defense against virus attacks,
unauthorized intrusions, and ﬂooding of harmful traffic, for successfully managing, monitoring,
and maintaining a healthy network.
Enterprise-Class Firewall Security
The D-Link NetDefend Unified Threat Management (UTM) firewalls provide a powerful security solution to protect business networks from a wide variety of threats. UTM Firewalls offer a comprehensive defense against virus attacks, unauthorized intrusions, and harmful content, successfully enhancing fundamental capabilities for managing, monitoring, and maintaining a healthy network.
Unified Threat Management
NetDefend UTM Firewalls integrate an intrusion detection and prevention system, gateway antivirus and content filtering for superior Layer 7 content inspection protection. An acceleration engine increases throughput, while the real-time update service keeps the IPS information, antivirus signatures, and URL databases current.
Powerful VPN Performance
NetDefend UTM Firewalls offer an integrated VPN Client and Server. This allows remote offices to securely connect to a head office or a trusted partner network. Mobile users working from home or remote locations can also safely connect to the office network to access company data and e-mail. NetDefend UTM Firewalls have hardware-based VPN engines to support and manage a large number of VPN configurations.
Web Content Filtering
Web Content Filtering helps administrators monitor, manage, and control employee usage of and access to the Internet. The NetDefend UTM Firewalls implement multiple global index servers with millions of URLs and real-time website data to enhance performance capacity and maximize service availability.
Maintaining an effective defense against the various threats originating from the Internet requires that all three databases used by the NetDefend UTM Firewalls are kept up-to-date. In order to provide a robust defense, D-Link offers optional NetDefend Firewall UTM Service subscriptions which include updates for each aspect of defense: Intrusion Prevention Systems (IPS), Antivirus and Web Content Filtering (WCF). NetDefend UTM Subscriptions ensure that each of the firewall's service databases are complete and effective.
Robust Intrusion Prevention
The NetDefend UTM Firewalls employ component-based signatures. A unique IPS technology which recognizes and protects against all varieties of known and unknown attacks. This system can address all critical aspects of an attack or potential attack including payload, NOP sled, infection, and exploits.
Stream-Based Virus Scanning
The NetDefend UTM Firewalls examine files of any size, using a stream-based virus scanning technology which eliminates the need to cache incoming files. This zero-cache scanning method not only increases inspection performance, but also reduces network bottlenecks.
Powerful VPN Engine
Hardware-based data encryption and authentication for IPSec, PPTP, and L2TP in Client/Server mode enable fast and safe handling of VPN traffic. The Professional Intrusion Prevention System (IPS) automatically updates from a comprehensive IPS signature database focusing on attack payloads to protect the network against zero-day attacks.
Fast, Efficient Web Content Filtering
Multiple index server implementation, granular policies, black lists and active content handling enhance performance and effectiveness of web surfing control.
Acceleration Engine for Unified Threat Management
A powerful processor allows the firewall to carry out IPS and Antivirus scanning simultaneously without affecting performance.
Licensed for Unlimited Users
Optional subscription services for IPS, Antivirus Scanning and Web Content Filtering are priced per firewall rather than per user, thus reducing the total cost of ownership for licensing.
WAN Link Load-Balancing and Fault-Tolerance
Multiple WAN ports support traffic load balancing and failover, guaranteeing Internet availability and bandwidth.
